519111 - Add Project IDs to StageMetricsResolver

What does this MR do and why?

Value stream stage metrics do not support filtering by project ID when using GraphQL. This does not match the functionality of the REST api currently used on the page. Adding it to the StageMetricsResolver will help with the alignment

How to set up and validate locally

• Open http://gdk.test:3000/-/graphql-explorer
• Run two queries, one with group resourceType and one with project resourceType

{
  group(fullPath: "flightjs") {
    id
    valueStreams {
      nodes {
        stages(id: "gid://gitlab/Analytics::CycleAnalytics::Stage/18") {
          id
          name
          metrics(
            projectIds: ["gid://gitlab/Project/7", "gid://gitlab/Project/24"]
            timeframe: {
              start: "2024-11-01",
              end: "2025-01-31"
            }
          ) {
            series {
              averageDurations {
                date
                value
              }
            }
          }
        }
      }
    }
  }
}

{
  project(fullPath: "flightjs/Flight") {
    id
    valueStreams {
      nodes {
        stages(id: "gid://gitlab/Analytics::CycleAnalytics::Stage/18") {
          id
          name
          metrics(
            projectIds: ["gid://gitlab/Project/7", "gid://gitlab/Project/24"]
            timeframe: {
              start: "2024-11-01",
              end: "2025-01-31"
            }
          ) {
            series {
              averageDurations {
                date
                value
              }
            }
          }
        }
      }
    }
  }
}

The group should return back data under valueStreams while project should throw an error
